Genes affected
ADAM33 (HGNC:15478): (ADAM metallopeptidase domain 33) This gene encodes a member of the ADAM (a disintegrin and metalloprotease domain) family. Members of this family are membrane-anchored proteins structurally related to snake venom disintegrins, and have been implicated in a variety of biological processes involving cell-cell and cell-matrix interactions, including fertilization, muscle development, and neurogenesis. This protein is a type I transmembrane protein implicated in asthma and bronchial hyperresponsiveness. Alternative splicing results in multiple transcript variants encoding different isoforms.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 25, 2023The c.1619C>T (p.A540V) alteration is located in exon 15 (coding exon 15) of the ADAM33 gene. This alteration results from a C to T substitution at nucleotide position 1619, causing the alanine (A) at amino acid position 540 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
